Rascal Flatts were named favorite country group, and also won the Text-In Award, determined by text messages sent by the show's viewers. Blige won for favorite female artist and favorite album ("The Breakthrough"), both in the soul/R&B categories. Clarkson won for favorite female pop/rock artist and favorite adult contemporary artist.
Actor Jamie Foxx picked up a statuette -- for favorite soul/R&B male artist -- to add to the Academy Award he won last year for his role as Ray Charles in "Ray."
"This means a lot more than you think," said Foxx, accompanied by his biological mother, whom he said he had not seen in years.
Another "American Idol" victor, Carrie Underwood, won the prize for breakthrough artist.
